The Influence of Organic Matter on Soil Compactibility and Air Permeability of some Soils in Borno State	2004	8	.pdf	application/pdf	3451	196	61	The degree to which soil compaction affects soil physical properties and consequently crop yields is dependent upon soil type, the number of tractor passes, tyre contact pressure, soil moisture content at the time of compaction and crop type (Voorhees, 1977; Oni and Adeoti, 1986; Ohu and Folorunso, 1989). Soil compaction reduces soil porosity and thereby deteriorates soil aeration by curtailing the exchange of air from the root zone with air from the surface (Negi et al., 1980).	cache/azojete-324.pdf	txt/azojete-324.txt
